G7 for 180gr SMK

[Quickoz]

Hoping Bryan Litz can answer this for me or anyone with his book. Chasing the most upto date G7 for the 7mm 180gr SMK. Also the spec OAL of the bullet.

Cheers.

Take the G7 value for the 180 hybrid and multiply by 1.04. This should be very close.

Why 1.04? Your saying it should be higher then the 180gr Hybrid?

Bryan's second edition book, "Applied Ballistics for Long-Range Shooting" only lists 7mm SMKs up to 175 Gr. The G7 BC for this bullet is .327 average. The bullet OAL is 1.453.
Again this is for a 175 and not 180 so probably does not help much??
